Rita Bjorg,
You could hit the Elk river near Elkton, MD.
Also the Bohemia river and the Sassafras rivers in MD. All mostly fresh or brackish water. Try contacting Chessie marine, they are the closest and largest dealer to that area.
www.chessiemarine.com They handle Nautique and Centurion.
Do you have your own boat?
